Benadryl is fine for kitties ... and the best thing for allergic reactions. Well, let me double check ... I know it is "ok" for dogs, let me check again for cats.... BRB!

OK, here is one statement

What can I do if an insect bites my dog or cat?

If there is swelling around the face or eyes, a common symptom of an insect bite, you can give Benadryl at the dose of 1 mg/pound. That means 1 Benadryl pill for every 25 pounds of body weight. If you have a cat, it is best to purchase tablets and give one-half tablet. If symptoms persist, you should consult a veterinarian.
